Tower Stack
About Tower Stack
Tower Stack is our own one-tap stacker. A block slides across the screen and you tap to drop it. Whatever hangs over the edge of the block below gets sliced off and falls away, so the tower narrows as it climbs. Land one dead centre and you get the width back plus a bonus.
How to play
Tap to drop the moving block. Any part that overhangs the block below is cut off and the tower gets narrower. Land it perfectly aligned and you win width back instead of losing it.
Controls
- Tap anywhere to drop the block
- Space bar on a keyboard
What makes it worth playing
- One input, so there is nothing to learn
- Overhang is sliced off, so mistakes compound visibly
- A near-perfect drop restores width instead of taking it
- The tolerance for a perfect drop scales with the block, so it stays achievable when the tower is wide
- Drawn in code, no assets, instant start
- Best height saved on your device

Tips from playing it
- Aim at the trailing edge, not the centre. The block is still moving when you tap and there is a frame of travel between your thumb and the drop.
- Chase perfect drops early while the block is wide and the tolerance is generous. That is where you bank the width you will need later.
- When the tower gets thin, stop going for perfect and just stay on the block. Surviving is worth more than a bonus you will miss.
- The rhythm is constant. Counting the sweep is more reliable than reacting to it.
Notes from building it
The perfect-drop tolerance is the one number that decides whether this genre feels good or cheap. Set it as an absolute pixel value and it behaves completely differently at the top and bottom of a run: generous when the tower is wide, impossible when it is narrow, which is exactly backwards from what a player expects. Ours is proportional to the current block width, with a small absolute floor so it never shrinks to nothing. The practical effect is that a perfect drop stays a real possibility the whole way up, and the reward for it is the width back plus a bonus, which means a skilled run can recover from a bad drop instead of just decaying to zero. Without that recovery the game is a countdown, and a countdown has no comeback story in it.
